To all whom it may concern:

Be it knownthat I, James H. WAGEN- Hoxs'r, a citizen of the UnitedStates, residin at, Akron, in the-county of Summit and tate of Ohio,have invented a certain new and useful Improvement in Wheels withDemountable Tire-Carrying Rims, of which the following is full, clear,and exact description, reference being had tQ' the accompan ing drawngs.

is invention relates to wheels and dev :7 mountable "tire carrying rimsadapted ,for

" use in connection with said wheels.

' The objectof the invention is to provide a wheel body which shall belight, strong, and durable and which will lend itself for use inconnectionwith demountable tire carrying rims.

' moved Another object of the invention is to pro vide a demountabletire carrying rim w ich can be uickly and easily laced upon or refromthe wheel body. A stlll further jobject is to provide a rim in which theinwheel body. 1

ternal pressure of the tire carried thereon will assist in maintaining.the rim upon the Anotherobject of th e invention is to pro- 1 vide atire carr ing rim in which a mini mum number 0 parts will be r uired toositivelyv secure the rim upon t e wheel y. Another object of theinvention is to provide a tire carrying rim embodying all of thesecharacteristics and which can be adapted foruse with either a straightside- .or clincher tire.

With these various objects in view and certain others which will becomeapparent as the description proceeds, the'invention "consists 1n thenovel features of construction and in the mannerof comblmng the same,

all of which will be fully described herein-' after and set forth in theappended claims. In the drawings forming a part of this ecification,Fig. 1 is a face view of a w eel body and demountable tire carrying rimarranged thereon and embodying one form of 1 ny invention; Fig. 2 is adetail sectional view showing one form of rim in engagement with oneformof fixed rim Fig. 3 is' y a similar view showing the means forfasteni the demountable tire carrying rim to the w 'eel'body Fig. 4 is adetail view show- .ing a section of the tire carr ing rim, the fixed rimand the clamping ug, these various parts'being disconnected; Fig. 5 is adetail show ng the demountable t re carrying rim and clamping ificationof the fixed rim and Figs. 12 and 13 are detail sectional structures ofthe forms shown in 7-11 inclusive.

In constructing a wheel body in accordance with' my invention I employ aplurality of wooden spokes A and a sheet metal fixed mm B, this sheetmetal fixed rim being connected to the spoke ends in any suitablemanner. 'The fixed rim B is channeled, as shown, and the inner 1ethereof, is rovided with an inwardly exten ing flange 8, is preferablycurved slightly to conform to the curve of the tire carrymg rimhereinand 6,-or it may be made with an inwardly which PATENT joF IcE.

ig. 8 is a new similar to Fig. 5 showso' I.

, after referred to. The outer leg of thefixed Z rim 1s of less heightthan the inner leg'and may provided with a straight outwardly" extendingflange D, as shown in Figs. 2, 3,

extending and inclined flan e E as shown in Figs. 7-13. Transverse b0 tsF are passed -through-the-fixed rim at definite points, the

outer ends of the bolts being threaded to re- ;ceive the nuts G and theouter leg and flange are pressed inwardly at points inv line with thetransverse bolts for a after ex lained.

H in 'cates the tire carrying rim which can be of the clincher e orstraight side type. Rigidly connect rim are t butt welded to the rim andhaving an inward- 1 1% and throug which the threaded ends of thebolts Fpass, the nuts being then screwed purpose hereinextending ortion'apertured as shown attothe tire carrying i e clamping lugs I, said lugsbeing on to securely fasten the demountable tire 'carrying hrim to thefixed rim ofthe wheel body. e inner portion of the rim is preferablycurved to correspond with the curved flange C .of the fixed rim. Theouter portion of the tire carrying rim is provided'with an inwardlyextending rib L which is adapted to rest upon the flange D or Eandcomp'em sates for thedifierence in height of the egs of the fixedrim- Thi rib L m y e n he 2, 3, 9, and 10, the clamping lug form oianinrolled bead as e, at, 7, and 10.

In the forms of rims illustrated shown in Figs.

in Figs. is welded to the base of the rim. In all instances it is buttwelded and to facilitate this operation the clam ing lug is preferablyformed with protru mg portions 1 and one of these protruding portionscontacts with the 'inrolled bead or other form of inwardly projectingrib, and during the welding process these protuberances and thecontiguous portions of the bead or rib become flattened so to intimatelyunite the clamp to the base of the practice. ll prefer to employ fourclamping lugs, adjacent each end of the transplit tire carr ing rim andthe other two at equidistant points from said iirst mentioned lugs andabout therefrom. The openin s or apertures K in the end lugs are sligtly elongated circumferentially to permit a limited expansion of the rimwhen being fastened upon the wheel body, but the other two lugs may havethe usual round holes to receive the bolt ends.

As previously stated the outer flange and leg are pressed inwardly, thisbeing done to provide space or clearance for the reception the clampinglugs, and in Figs. 11 and 13 the outer leg oi the fired rim is formedwith an outwardly extending ledge or foot piece hi against which theinner end of the clamping lug can be brought to bear.

in operation a pneumatic tire is placed upon t e tire carrying rim andthe tire carrying rim with tire thereon is then laced upon the fixed rimor" the wheel bo y the diziferential heights oi the legs of the fixedrim permitting the tire carrying rim to be freely placed upon the fixedrim the bolt ends will pass through the apertures in the clamping lugs,and then by applying the nuts and tightening the same the rim will hebrought into a true plane, the inner side of the rim contacting with theinner flan e of the fixed rim while the inrolled head or rib willcontact with the outer flange, the rim being drawn inwardly at thepoints of fastening and it is obvious that when the nuts are properlytightened the rim will be securely fastened, holding the same in a trueplane and at the same time providing the necessary driving connectionbetween the wheel rim and tire. The inter-- nal tire pressure willprevent any considerable separation of the rim ends, but willmes esermit a slight separation as the rim is astened upon the wheel body; butthe constant interior ressure of the tire will serve to maintain rm andpositive contact of the rim against the wheel body. In other words, thetire ressure is constantl acting to contract the rim whereas theastening means tends to exert force in the opposite directiom By thesetwo forces actmg against one another a firm contact and fastening isobtained with the aid of the minimum number of parts.

It will be understood that while I have shown and described certainpreferred forms of construction of the various there can be variouschanges or modifications of said parts within the scope of the ap endedclaims.

aving thus described my invention, what I claim 1s:

1. The combination with, a wheel body having a channeled sheet metalfixed rim provided with rim supporting flanges, of

parts a one piece transplit tire carrying demountable rim, clamping lugsrigidly connected.

to said rim, transverse bolts passing throu h thelixed rim and throughopenings in t e inner ends of said clamping lugs, nuts upon said bolts,the openings in the clamping lugs adjacent the s lit in the'tirecarryingrim being elongate 2. The combination with a wheel body having achanneled sheet metal fixed rim having rim supporting flanges, of a onepiece transplit tire carrying rim, spaced clamping lugs connected tosaid rim, transverse bolts passing through the fixed rim and throughopenings inthe clamping lugs, nuts upon-the ends of said bolts, two ofsaid clam s being arranged adjacent the split in the rim and uponopposite sides of said split.

3. The combination with a wheel body having a channeled sheet metalfixed rim having rim supporting legs provided withmy signature.
